Higher Order Nonclassicality from Nonlinear Coherent States for Models with Quadratic Spectrum
Autor: Anaelle Hertz, Sanjib Dey, Véronique Hussin, Hichem Eleuch
Publikováno v: Symmetry, Vol 8, Iss 5, p 36 (2016)
Harmonic oscillator coherent states are well known to be the analogue of classical states. On the other hand, nonlinear and generalised coherent states may possess nonclassical properties. In this article, we study the nonclassical behaviour of nonli

Policy proposals to promote inclusion of caregivers in the research funding system: a call for change
Autor: Isabel L Torres, Rayven-Nikkita Collins, Anaelle Hertz, Martta Liukkonen
The COVID-19 pandemic has unmasked a deeply flawed research funding system riddled by inequitable policies, biased evaluations, and a lack of transparency and accountability. While most scientists were affected by the pandemic to some extent, evidenc

Realignment separability criterion assisted with filtration for detecting continuous-variable entanglement
Autor: Matthieu Arnhem, Ali Asadian, Nicolas J. Cerf, Anaelle Hertz
We introduce a weak form of the realignment separability criterion which is particularly suited to detect continuous-variable entanglement and is physically implementable (it requires linear optics transformations and homodyne detection). Moreover, w

Relating the Entanglement and Optical Nonclassicality of Multimode States of a Bosonic Quantum Field
Autor: Stephan De Bièvre, Anaelle Hertz, Nicolas J. Cerf
Publikováno v: Physical Review A
Physical Review A, American Physical Society 2020, ⟨10.1103/PhysRevA.102.032413⟩
Physical Review A, 2020, ⟨10.1103/PhysRevA.102.032413⟩
The quantum nature of the state of a bosonic quantum field manifests itself in its entanglement, coherence, or optical nonclassicality which are each known to be resources for quantum computing or metrology. We provide quantitative and computable bou

Quadrature coherence scale driven fast decoherence of bosonic quantum field states

Phys.Rev.Lett., 2020, 124 (9), pp.090402. ⟨10.1103/PhysRevLett.124.090402⟩
Physical Review Letters, 2020, ⟨10.1103/PhysRevLett.124.090402⟩
We introduce, for each state of a bosonic quantum field, its quadrature coherence scale (QCS), a measure of the range of its quadrature coherences. Under coupling to a thermal bath, the purity and QCS are shown to decrease on a time scale inversely p

Comparing Entanglement and Optical Nonclassicality of Bosonic States
Autor: Stephan De Bièvre, Nicolas J. Cerf, Anaelle Hertz
Publikováno v: OSA Quantum 2.0 Conference.
Entanglement, coherence and optical nonclassicality, all reveal the quantum nature of a state and can be viewed as a resource for quantum computing. We provide quantitative and computable bounds relating those quantities.

Continuous-variable entropic uncertainty relations
Autor: Anaelle Hertz, Nicolas J. Cerf
Publikováno v: Journal of Physics A: Mathematical and Theoretical
Uncertainty relations are central to quantum physics. While they were originally formulated in terms of variances, they have later been successfully expressed with entropies following the advent of Shannon information theory. Here, we review recent r

Multidimensional entropic uncertainty relation based on a commutator matrix in position and momentum spaces
Autor: Luc Vanbever, Nicolas J. Cerf, Anaelle Hertz
The uncertainty relation for continuous variables due to Byalinicki-Birula and Mycielski expresses the complementarity between two $n$-uples of canonically conjugate variables $(x_1,x_2,\cdots x_n)$ and $(p_1,p_2,\cdots p_n)$ in terms of Shannon diff

Detection of non-Gaussian entangled states with an improved continuous-variable separability criterion
Autor: Nicolas J. Cerf, Evgueni Karpov, Anaelle Hertz, Aikaterini Mandilara
Publikováno v: Physical Review A. 93
Currently available separability criteria for continuous-variable states are generally based on the covariance matrix of quadrature operators. The well-known separability criterion of Duan et al. [Phys. Rev. Lett. 84, 2722 (2000)] and Simon [Phys. Re
